Este protocolo descreve um ecrã de alta taxa de transferência para a atividade celulolítica de uma biblioteca metagenomic expressa em Escherichia coli. A tela é solução baseada e altamente automatizado, e usa um pot-química em 384 microplacas bem com a leitura final como uma medida de absorbância.

This article summarizes general design principles for functional metagenomics. The focus is on Escherichia coli as an expression host, although alternative host-vector systems are discussed in relation to optimizing gene recovery in activity-based screens. Examples of DNA isolation and enrichment approaches, library construction and phenotypic read-out are described with special emphasis on the use of high throughput technologies for rapid isolation of environmental clones encoding phenotypic traits of interest.
